6 Claims.

This invention relates to improved means for raising and lowering, awindow sash, and is especially adapted for use in connection with buses.

It happens many times that it is desirous for a bus driver to raise andlower the window adjacent his seat, and in order that this may be donewith the least effort on the drivers part and without drawing hisattention away from the path of movement of the vehicle or itsoperation, I have provided, as the principal object of my invention,means whereby the driver may, with one hand-the left'reach over to thewindow and engage my improved type of operating means without taking hiseyes from the path of movement of the Vehicle and without interferingwith the work being done, if any, by his right hand or his feet.

My improved type of window sash operating means will be readilyunderstood by refernce to 20 the annexed drawing, wherein:

Figure 1 is an inside View of the window which, in the case of a bus, ison the left of the drivers seat.

Figure 2 is a vertical, sectional view through the lower part of thewindow sash and frame.

Figure 3 is a transverse part-sectional and 'pa'rt-elevational plan Viewon the line 33 of Figure 1.

Figure 4 is an enlarged View of the right-hand so lower corner of Figure1.

In the drawing, l and 2 are window frame members having stops 3 and 1thereon. The window frame carries a window sash, the bottom rail, 5, ofwhich carries a weather strip 6 adapted 35 to engage the ledge I on thewindow frame. The

rail 5 carries a glass pane 8.

Attached to the opposite ends of the bottom rail 5 of the window sashare brackets 9 and I0, being held in position by any satisfactory meansas by screws II. On each of the brackets 9 and It is respectivelymounted a lever l3 and lit, the mounting being pivotal in form as shownat M so that each lever may have a rotatable motion about its pivot M.Also pivotally mounted on each of the brackets 9 and it, as by a pivotpin I5, is a catch l6 having one end H extending over its side framemember I or 2. The other end I8 of the catch member l6 extends intooverlapping relationship with the end of the lever H. as clearly shownin Figures 2 and 4. A spring E9 is carried by the window sash rail 5 atopposite ends thereof and acts on its respective catch member end 58 tonormally hold the catch so that the end H is in contact with its 0Window frame member I or 2.

Each of the levers i2 and i3 is provided with a hub portion adapted tosnugly fit within a tubular handle member 2! which, as will be seen fromFigure 1, extends nearly the full length of the rail 5.

When it is desired to raise the window, all the operator, in the case ofa bus, has to do is to move his hand over to the window and grasp thehandle 2| and merely lift on the window until the ends H of the catchesit slide over the inclined surfaces 22 of the stop members 3 and 4, whenthe spring l5 will'move them into locking position over the top part ofthe stops. In order to lower the window, all the operator has to do isto reach over to the window and engage the tubular handle 2! at anyposition along its length, without looking to see where it is, and pulldownwardly thereon. This will cause the levers l2 and I3 to turn abouttheir pivots l4 and this will oscillate the catch members I 5 abouttheir pivots l5, releasing the engaging ends I? of the catches from thestops 3 and 4 and allowing the window to be easily pulled to closedposition.

While I have shown a pair of stops 3 and 4, it is to be understood thatthere may be as many pairs of stops arranged along the window frame asare desired.

From what has been said, it will be readily understood that the meansdescribed for raising and lowering the window sash is highlyadvantageous when used on a bus, as the window may be raised and loweredwith one hand without taking the operators attention away from the pathof movement of the vehicle.

While I have particularly described the application of my invention to abus window which is opened by raising the lower sash, it is equallyapplicable to a window which is opened by dropping the upper sash; thatis to say, a window which is opened by pulling down on the bar handle.Other applications of its use will be apparent to one skilled in thisart.

What I claim is:

1. An operating means for raising and lowering a window sash comprisinga handle member extending across the lower part of the sash and beingrotatably mounted thereon, a catch member oscillatably mounted on thewindow sash adjacent the end of said handle member and having one endoverlapping a member of the window frame having a stop located adistance above the catch and in the path of movement thereof, a leveroperatively connected to said handle extending into operative relationto the opposite end of said catch member, and means for normally holdingat least the lever and catch so the latter will positively engage saidframe stop when the sash is raised to catch position.

2. An operating means for raising and lowering a window sash comprisinga bar type handle member extending across a greater portion of thebottom of the window sash and being rotatably mounted at its oppositeends on the sash, a catch member oscillatably mounted on the sashadjacent the opposite ends of said handle member, each catch memberhaving one end overlapping a member of the window frame having a stopfor each catch located a distance above the catches and in the path ofmovement thereof, a lever at each end of the handle bar and positionedin operative relation thereto, each lever extending into operativerelationship with its cooperative catch, and spring means for normallyholding the levers and catches so the latter will engage said stops onthe frame when the window is raised by the bar handle.

3. An operating means for raising and lowering a window sash as setforth in claim 2, characterized in that the bar handle is attached tothe levers so its axis is above the axis of the levers and to one sidethereof, whereby downward pressure on the bar handle at any point alongits length, to close the window, will easily rotate the levers and movethe catches from said stops when the window is in raised position. a

4. A window-sash-operating means including a single bar type handle forboth raising and lowering the window, the bar being positioned acrossthe lower part of the window sash, a pair of levers pivoted on oppositesides of the sash and supporting said bar, a catch located at each endof the bar and being oscillatably mounted and having one end positionedin operative engagement with its lever, while the other end of eachcatch extends over a part of the window frame, having stops to beengaged by said catches when the window is raised by said bar handle,and spring means acting to move said catches into stop-engagingposition.

5. A window-sash-operating means as set forth in claim 4, furtherdefined in that the levers and catches are positioned in overlappingrelationship in free-sliding position, while the bar handle ispositioned on the levers so a downward pullon the bar, when the'windowis in raised position, will rotate the lever to release the catches fromsaid stops.

6. A window-sash-operating means including a single bar type handle forlowering and raising a window, the bar being positioned across a railmember of the window, a pair of levers pivoted on opposite sides of thesash and supporting said bar, a catch located at each end of the bar andbeing oscillatably mounted and having one end positioned in operativeengagement with its lever, while the other end of each catch extendsover a part of the window frame having stops to be engaged by saidcatches for holding the sash in a predetermined position, spring meansfor normally keeping the catches in holding position,

the window being lowered by applying a downward-acting force on the bar,thereby causing the levers to move the catches to release positionallowing the window to be pulled down, while an upwardly applied forceon the bar raises the
